Calculated Fields
In the ABI worksheet, the following fields are calculated automatically. These calculated values automatically update when any of the source values are changed.
Field | Source Values | Calculation Logic |
|---|---|---|
ABI | Right and left brachial pressures, Posterior Tib pressure and Dors Pedis pressure | MAX Ankle Pressure ÷ MAX Brachial Pressure Note: MAX ankle pressure will use the higher pressure of the Posterior Tibial artery and Dorsalis Pedis artery. The higher of the two brachial pressures will be used. |
Rest TBI | Right and left rest brachial pressure, Toe pressure | Toe Pressure ÷ Brachial Pressure Note: If acquiring pressures for Great toe, 2nd toe, etc, TBIs will calculate individually for each toe using pressure acquired in that toe. The higher of the two brachial pressures will be used. |
